摘　　要：[目的]调查慈溪海防林天牛危害树木种类,并研究天牛的防治方法。[方法]2009年,对慈溪主要防护林工程区及城市绿地、市林场开展野外调查,整理出天牛寄主树种名单,并列出遭受严重危害的林木种类。2021—2022年,对天牛寄主树种作了补充调查和资料完善。[结果]据野外调查,浙江慈溪沿海防护林天牛的寄主树种共73种,其中17种受害严重。经连续3年对天牛进行综合防控,林木天牛幼虫平均虫株率从35.70%下降到16.40%;田间林木天牛成虫虫口密度从1153.5头/hm^(2)下降到529.5头/hm^(2),降幅达54.10%,效果十分显著。[结论]综合应用药剂防治、人工杀灭和诱集树引诱集中防治等方法,有利于提高天牛防效。[Objective]The aim was to investigate the species of trees damaged by longicorn in coastal protection forest of Cixi and study the control methods of longihorn.[Method]In 2009,the field investigation was carried out in the main protection forest engineering area,urban green space and Cixi forest farm in Cixi,the list of host tree species of longicorn was sorted out,and the tree species seriously damaged were listed.From 2021 to 2022,supplementary investigation and data improvement were made on the host tree species of longicorn.[Result]According to field investigation,there were 73 species of host trees of longicorn in coastal protection forest in Cixi of Zhejiang province,among which 17 species were seriously damaged.After 3 years of comprehensive prevention and control,the average larval rate of longicorn in forest decreased from 35.70%to 16.40%.The population density of longicorn in forest decreased from 1153.5 to 529.5 per hectare,with a drop of 54.10%.[Conclusion]The comprehensive application of insecticide control,artificial killing and lure and concentration control with trapping trees are beneficial to improve the control efficiency.
